New Additions to the Interactive Math Page
I’ve added two new links to the Interactive Math page:
- Secant lines to tangent lines. Learn how secant lines (lines through two points on a graph) are used to introduce the derivative in calculus. You’ll get to interact with a graph and see how a tangent line (whose slope is the derivative) emerges by making the two points a secant line passes through closer together.
- The calculus of cooling coffee. Read about the calculus that helps explain why coffee cools down so quickly.
Both additions are related to content from my book, Everyday Calculus. Visit the Interactive Math page to find out more.
